Is it safe to ride the metro rail red line at like 4:30 AM?

I live in Northside and take the rail to work everyday. I would like to start working out at the Tellepsen YMCA in the morning but it doesn’t make sense to drive and park there just to drive back home and take the rail. Does anyone have any experience using the red line light rail at that time? I am not afraid of homeless people. Crackheads, yes. Sleeping homeless people trying to stay warm, no.
